## NAME

         printroot - print the name of the root device on standard output

## SYNOPSIS

         printroot

## OPTIONS

## EXAMPLES

## DESCRIPTION

         Printroot is useful for initializing the /etc/mtab  when  the  system  is
         booted.   It  figures out what the root device is by searching /dev until
         it finds a block special file with the right major/minor device numbers.
